Can I edit email addresses for exhibitor portals?

For Staff and Admin users:
You can change their email addresses by deleting and re-adding them to the portal.
Deleting and re-adding Staff or Admin Users will not affect your PLC license.

For Primary users:
Primary users' emails cannot be edited.

The only way to change them is to delete the portal from the builder and regenerate it.
Note: Deleting the portal will affect your PLC license.
